ARM: keystone: Add minimal TI Keystone platform support Texas Instruments Keystone family of multi-core devices are based on ARM Cortex A15. Patch adds basic definitions for a new Keystone sub-architecture in ARM. The TCI66xxK2H Communications Infrastructure Keystone SoCs are member of the C66x family based on TI's new KeyStone 2 multi-core SoC Architecture designed specifically for high performance wireless and networking infrastructure applications. The SOCs contains many subsystems like Cortex A15 ARM CorePacs, C66XX DSP CorePacs, MSMC memory controller, Tera Net bus, IP Network, Navigator, Hyperlink, 1G/10G Ethernet, Radio layers and queue based communication systems.

clocksource/drivers/keystone: Add the COMPILE_TEST option Change the Kconfig option logic to fullfil with the current approach. A new Kconfig option is added, CONFIG_KEYSTONE_TIMER and is selected by the platform. Then the clocksource's Kconfig is changed to make this option selectable by the user if the COMPILE_TEST option is set. Otherwise, it is up to the platform's Kconfig to select the timer.

ARM: Keystone: Enable ARCH_HAS_RESET_CONTROLLER The Keystone 2 family of SoCs will use various Reset Controller drivers for managing the resets of remote processor devices like DSPs on the SoC, so select the ARCH_HAS_RESET_CONTROLLER option by default to enable the Reset framework.

soc: ti: Add ti_sci_pm_domains driver Introduce a ti_sci_pm_domains driver to act as a generic pm domain provider to allow each device to attach and associate it's ti-sci-id so that it can be controlled through the TI SCI protocol. This driver implements a simple genpd where each device node has a phandle to the power domain node and also must provide an index which represents the ID to be passed with TI SCI representing the device using a single phandle cell. The driver manually parses the phandle to get the cell value. Through this interface the genpd dev_ops start and stop hooks will use TI SCI to turn on and off each device as determined by pm_runtime usage.
